SPECIFICATION forming part of Letters Patent No. 224,495, vdated. February 10, 1880.

^ Appli-cation led November 21, 1879. I

To all whom-it may concern:

Be it known that I, CHARLES JAMES WAD- DELL, oi' Manchester, county of Lancaster, in the Kingdom of Great Britain and Ireland, have invented a new and useful'Improvement in Taps for Fluids, of which -the following is a speciiication.

My invention, which relates to taps for drawing oiI' fermented and other liquors from casks or other vessels, consists of a novel arrangement whereby such taps are less easily tampered with.

An example of a tap constructed in accordance with my invention is illustrated on the accompanying sheet of drawings, of which-Y Figure 1 is an outside viewof the tap 5' Fig. 2, a view of the front end. Fig. 3 is a vertical longitudinal section of the tap. Fig. 4 is a vertical cross-section at the lineA, Fig. 3, while Fig. 5 is a similar section at the line B, Fig. 3.

Fig. 6 is a separate View of the plug; and

lelastic pressure.

Figs. 7 and 8 are, respectively, anend view of the plug and a view in section at the line G, Fig. 6.

Referring to Fig. 3, a/.is the shell or body of the tap, and b is the plug. The said plug is conically formed, as is usual, and is provided with a shank, in which are cored or formed slots -or openings c, which communicate with a passage, d, formed in the plug. The conical seating for the plug, formed in the' body a, is arranged with its axis about in line with the main part of the body a,`the smaller end of the core being to the front of the tap, as clearly indicated in Figr3. The core or passage in the conical part of the body a is made sufficiently large for the plug to be passe through the said core into position.

The plug is retained'in position by means of a part, e, which is screwed linto the end of the passage in the body a. A washer, of leather,

cork, or other suitable material, isinterposed between the end of the part e and the end of the shank of the plug, ink order that the plug may be retained in position with a slightly It will be seen that the plug is entirely inclosed Within the body of the tap. When the tap is in use access can vonly be had to the end of the plug, which projects into a smallchamber, f, formed in the front end ot' the body a. The said front end of the plug is suitably` formed to be acted upon by means-of a key. In the example the end of the plug is formed with a stump to suit a barrel-,key and with a recess intoV which the bit of a key may enter.Y

It will'be seen that the front end of the body a is formed with a bayonet-joint key-hole having a slot Vfor the passage of the bit of the key h. When the key has been pushed in a short distance, as Vshown in dotted lines at Fig. l, its farther entry is arrested in consequence of the innerV part of the key-hole being, as it were, turned round to some extent, as indicatedl in Fig. 5. It is nownecessary to rotate the key h to thel extent of about a quarterturn when it maybe pushed inward till it engages with the plug of the tap. The keyway may be formedto require the key to be turned less ormore than is indicated. y The key can only engage with the plug when 'the outflowpassage gis turned away from the bib of the tap, and as a consequence it is impossible to withdraw the key without closing the tap.

Wards may be applied to the keyway to render it more difficult to open the tap without the proper key.

That part of my invention which relates to the keyway is also applicable to -taps having their plugs otherwise arranged than as indi-vv cated in thedrawings.

Access cannot be had to the plug to loosen Y it in its seating While the tap is in use; but when it is withdrawn from the cask the part c `can be unscrewed, and the parts be cleansed,

or the tightness of the plug in its seating can be regulated.`

The formof the tap renders it less liable to `injury when being driven into the cask.

The barrel or Seating into which the plug fits may be lined with cork or with any other suitable material if considered to be advisable.

' I claimas my invention- 1. The combination of the shell of the tap,

having a side outlet or bib, with the longitudinal plug b, having a corresponding out flow-opening, g, the screw in the inner end of In testimony whereof1 I have signed my the tap, and a key adapted to the outer end name to this specification in the presence of of' the plug, all substantially as set forth. two subscribing witnesses.

2. The combination of the shell of the tap, 5 having aside outlet; or bib, with the hollow CHARLES JAMES WADDELL.

longitudinal plug having a corresponding opening, g, and having its front end adapted Witnesses: to receive e. key, and the front end of the shell EDWARD K. DUTTON, y having a bayonet-joint keyway, constructed DAVID FULTON. 1o substantially as described.
